some Australian Cuvculionidge. 479 



Head with clearly defined punctures, smaller about base 

 than elsewhere; with a small, isolated, interocular fovea. 

 Rostrum twice as long as greatest width, which is in front 

 of antennae, from antennae to base decreasing in width, 

 and with punctures as on head, in front very shining and 

 with small and sparse punctures. Prothoraoc very flat, base 

 lightly bisinuate and twice the width of apex, which is some- 

 what elevated in middle ; sides strongly rounded at apex, 

 gently elsewhere, with numerous, distinct, non-confluent 

 punctures, of moderate size in middle, and small towards 

 sides ; with a feeble impunctate space along middle. Elytra 

 not much, but distinctly wider than prothorax, sides feebly 

 decreasing in width almost from base ; with rows of fairly 

 large round punctures, in shallow striae, becoming smaller 

 posteriorly, but the striae deeper ; interstices wider than 

 striae, each with a row of sparse minute punctures. 



Length (excluding rostrum) 4j mm. 



Hab. Queensland : Kuranda. 



In general appearance fairly close to indigens, but much 

 more depressed, punctures much smaller, rostrum narrower 

 and more shining, interocular fovea much smaller, &c. The 

 description of albertisi is rather unsatisfactory, but its pro- 

 thoracic punctures are evidently different to those of this 

 species, as Pascoe says of them, in comparison with those of 

 basalis, " magis sed irregulariter.'" Those of basalis being 

 *'in medio et lateribus extus grosse/^ Albertisi also has 

 apparently more o\ the elytra pale, and the two colours less 

 sharply defined than in the present species.

 jMesembrinocis, gen. nov. 



Head of moderate size, partly concealed from above. Eyes 

 rather large, round, coarsely facetted, not close together. 

 Rostrum slightly longer than prothorax, rather wide, sub- 

 parallel-sided, lightly curved. Scrobes narrow, deep, oblique, 

 open posteriorly, and extending almost to lower edge of eyes. 

 Antennae moderately thin, inserted about one-third from 

 apex of rostrum ; scape almost straight, slightly shorter 

 than funicle and club combined ; first joint of funicle long, 

 second moderately long, the others short; club elliptic- 

 ovate, almost the length of funicle. Prothorax lightly
